ADJUSTABLE CHAIR.

Appiication med November is, 1921. serial no. 516,083.

To all 'whom t may concern.' j

Be it known that I, LOUIS FEAsnr., a citi zen of the United States, residing at Sturgis, county of St. Joseph, State of Michigan, have invented certain new and useful Improvements in Adjustable Chairs, of which the following is a specication.

This invention relates to improvements in adjustable chairs.

The main objects of the invention are:

First, to provide in an adjustable chair an improved means for adjustably supporting the back.

Second, to provide in an adjustable chair having means for adjustably supporting the back an improved control means.

Third, to provide in an adjustable chair an improved foot rest.

Further objects. and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the ob-jects of the invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of the invention is clearly illustrated in the acco-mpanying drawing, forming a part of this application, in which;

Fig. I is a side view of my improved adjustable chair partially broken away and in vertical section to better illustrate structural details.

Fig. II is a rear elevation.

Fig. III is a horizontal section on a line corresponding to line 3-3 of Figs. I and V, showing details of the back supporting means.

Fig. IV is a detail view partially in vertical transverse section on a line corresponding to line 4 4 of Figs. I and III, showing details of the control means for the adjustable back.

Fig. V is a detail view partially in vertical section on a line corresponding to line 5-5 of Figs. IIT,."III and.IV, showing details of the back supporting means, the b-ack being shown in its forward or upright position.

Fig. VI is a fragmentary section corresponding to that of Fig. V with the back in its rear or inclined position.

Fig. VII is a detail section on aline corresponding to line 7 7 of Fig. IV, showing details of the finger lever.V

Fig. VIII is a rear View of the back removed from the frame, the upper portion of the back being broken away.

Fig. IX is a fragmentary view partially in section illustrating one of the hinges or pivots for ythe back. y

Fig. X is a detail section on a line corresponding to line 10-10 of Figs. IX and XI.

Fig. XI is a detail section on a line corresponding to line 11-11 of Fig. X.

Fig. XII is a fragmentary View partially in vertical section on a line corresponding to line 12-12 of Fig. XIII, showing details of the foot rest, the foot rest slide being shown in its extended position, the foot rest proper being shown collapsed in full lines and in erected position by dotted lines.

Fig. XIII is a detail transverse section on a line corresponding to line 13%13 of Fig. XII. x

In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents lie frame generally, and 2 the adjustable ack.

The frame comprises the uprights or corner members 8 connected by side bars 4, front bar 5 and rear bar 6. The arms 7 are mounted upon the upper ends of the posts.

vThe back comprises the 'side pieces 8 con\ nected by the cross pieces 9. The back is provided with hinge members 10 having projecting headed pivot studsll which are secured to the outer sides'of the uprights of the side bars 8 at their lower ends thereof, the studs l1 being supported by the socket `l2 secured on the inner sides of the rear posts or luprights 3 of the frame. 'I he heads of these pivot Vstuds are elongated and they are beveled on their inner sides, as at 13, the sockets being beveled, as at 14, so that when the heads are engaged with the sockets they draw into the sockets. The heads, being oblong, may be introduced into the socket openings l5 when presented lengthwise thereto and when turned are engaged with the sockets.

The back is provided with a downwardly projecting arm 16 having upwardly projecting angle-shaped securing arms 17 on the rear side thereof Yengaging the under sides of the," cross bars'9 of the Iback and secured thereto by the screws 18,-see Figs. IV and V.

The arm 16 has a rearwardly curved lower end 19 with a segmental slot 20 therein. This slot 2O is engaged by the pin' 21 carried by the toothed slider22. This slide 2-2 is mounted upon the supporting bar 23 extending from the front cross piece of the frame. rlhe teeth 24 of the slide face upwardly. The slide is guided and supported on ythe support 23 by the inverted U-shaped sheet metal housing 25 having laterally projecting ears 2G by means of which it is secured to the slide,-see Fig. III. .The housing has a notch 27 through which the detent 28 engages the slide.

The detent 28 is pivoted at 29 at the side of the housing and is urged into engagement with the slide by the coiled spring 30. The detent is controlled from the ingerpiece 31 pivoted at 32 onfthe under side of one of the arms 7, the finger piece being disposed transversely of the arm so that it may be engaged or grasped with the ngerof a hand resting upon the arm.

The inner end of the linger lever is connected 'by the link 33 to a lever 34 mounted on one of the side lpieces 4 of the frame below the finger piece, the side member having a recess 35 therein in which the lever projects, the lever being pivoted at 36 on a bracket 37 mounted on the inner side of the side piece 4.

The lever 34 is connected by the link V33 to the detent 28. y

AlVith this arrangement, when the outer end of the finger lever is pressed upwardly, as can be conveniently done by resting. the hand upon the arm and grasping the lever, the detent is withdrawn from the slide permitting the adjustment of the back. As soon as the lever is released, the detent is engaged with the slide by means of. the spring 30.

I preferably provide a foot rest consisting of the sheet inetal slide 39 having upturned flanges 40 kat the edges thereof coacting with the channel-shaped slideways 41 mounted on the inner sides of the side pieces 4 of the frame. The slide 39 is provided with a cross piece 42 at its front end. Th'efoot rest 43 is provided with arms 44 which are pivoted in the flange portions of the slides so that the foot rest may be collapsedV upon the bottom of the slide, as

shown in Fig. XII, or drawn forwardly to erected position resting upon the cross piece 42, as shown by dotted lines in Fig. XII. The foot rest also serves as a tray or receptacle for books, newspapers'and the like.

I have illustrated my improvements in anY embodiment which I have found very satisfactory. I have not attempted to ill-ustrate or describe certain modifications or adaptations which may be desirable, as I believe the disclosure made will enable those skilled in the art to which this invention relates to embody or adapt my improvements as may be desired. f

Having thus described my invention, what I claim as new and desire to secure by Letters Pat-ent, is: Y

1. In a chair, the combination with a frame comprising side bars, arms, and a supporting bar extending from front to rear, of an adjustable back pivotally mounted on said frame, a downwardly projecting arm on saidA back provided with a curved lower end having a segmental slot therein, a toothed slide mounted on said bar and having a pin engaging said slot in said arm, an inverted U-shaped housing embracing said slide and having a transverse slot therein, a detent pivotally mounted on said supporting bar at the .side of said housing to engage said slide through said slot in said housing, and means for manually releasingsaid detent. Y

2. In a chair, the combination with a frame comprising a supporting bar extending from front to rear, of an adjustable back pivotally mounted on said frame, a downwardly projecting arm on said back provided with a curved lower end having a segmental slot therein, a slide mounted lon said bar and having. a pin engaging said slot in said arm, a detent mounted on said supporting bar to coact with said slide, and means for manually releasing said detent.

3. In a chair, the combination with a frame, of an adjustable back pivotally mounted on said frame, a downwardly prdjecting arm on said back provided with a curved lower end having a segmental slot therein. a slide mounted on said frame and having a pin engaging said slot in said arm, and means for adjustably supporting said slide.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
